Rather than letting cardboard go to waste in your home, you can turn cardboard into great STEAM projects. Not only can you learn something new and get those creative juices flowing but you’re also recycling. Win/win for everyone and the environment! Check out some favorite projects below, from engineering projects, to cardboard crafts, to science, and math, too.
